IMPROVEMENT '1N WOOD-SPLITTING MACHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEONARD TILTON, of Brooklyn, E. D., inthe county of Kings, and State of New York, have invented a new and improved Machine for Splitting Wood; and do hereby declare that the following is a full, clear, and exact description thereof, which-will enable others skilled in the art to make and usetbe same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a new and improved machine for splitting wood, and it consists in the employment or use of fixed cutters, a reciprocating hopper, and a vibrating or other moving bed, all arranged. to operate in the manner substantially as and for the purpose set forth.

In the accompanyingsheet of drawings Y Figure 1 is a longitudinal vertical section of myinvention, 'taken in the line z cv, iig. 2.

Figure 2, a transverse vertical section of the same, taken in the line yy, tig. 1.

Similar letters of reference indicate corresponding parts.

A represents a rectangular frame, having at its top two parallel horizontal rods, B B, which serve as ways or guides for a reciprocating box, C, having two vertical partitions, a a, within it, to form two hoppers,D D, in which the wood to be split is placed.` A V On the top of the box C, between the two partitions a' a, there is placed transversely a rock-shaft, E, having a pendent plate, 6, to the lower end of whicha bed, F, is attached, said bed being of V-shape in its transverse section, as shown clearly in iig. 2.

The lower part of the plate b has a journal, c, extending` from it, one from cach side, and these journals are fitted in fixed bearings, CZ, on the guide-rods B B.`

The boxV C is connected by rods G G to cranks H H, at the ends of a driving-shaft, I, at one end of the frame A, and by turning the shaft I a reciprocating motion is given the box C, and at the same time a vibrating or oscillating movement given the bed F, so that the latter will be movediirst under one hopper,and then under the other, the bed working on thejournols c as centres. v i

J J and K K are fixed cutters, secured firmly to cross-bars L L, which are permanently secured on the guide-rods B B. Theseeutters are all of V-form, as shown in iig. 2, the hollow or concave of the upper cutters J K being uppermost, and the hollow or concave of the lower cutters J' K being undermost, the angles of the upper and lower cutters being in close proximity to enchother.

The ends of the box e have V-shaped slots made in thcm, to allow the cutters to pass through, and the upper cutters are somewhat shorter than the lower ones J K, as shown in tig. 1. i

As the box C is movedLiirst in one direction and then in the other, one pair of cutters is made, at the com pletion of one stroke of the box, to extend entirely across one hopper, D, and at the completion of the succeeding stroke, the other pair of cutters is made to extend Aentirely across the other hopper. The hoppers D D are `filled with wood, the pieces being cut of a uniform length.A The pieces of wood, by the movement of th'e box C, are split, in consequence of being forced against the'cutters, the upper cutters J K not extending entirely through the wood, and consequently only checking the same, the complete cuts being given by the lower cutters J Kf, which sever the split portions entirely from the piecesor blocks.

The reverse positions of the cutter cause the wood to be split of the required degreeot` iineness, as the cuts of the lower cutters cross the checks ofthe upper cutters at right angles. While the cuts are being made, the Ilower pieces of wood are supported by the lower cutters J K', the wood in each hopper, when wound off from the cutters, being sustained by the bed F, which, by its oscillating movement, is made to pass from underneath the hopper that is being shoved against-the cutters, and underneath the upper that is being moved o` from them. This will .be understoodby referring to g. 1.

I would remark that one hopper, D, and one pair of cutters may be used for small machines, tol work with but little power, but in a quantity of cases the two hopper-s auditivo pairs of cutters would be the most durable machine. Y i

I do not claim separately the cutters J J K K', for they have been previously used, although arranged to operate entirely dierent from the nay herein shown and described, the cutter not being fixed; but

' I do claim as new, and desire to secure by Letters Patent- 1. The bed F, made V-shaped in its cross-section, and provided with the journals c and shank b, said bedbeing arranged tooseillate in eonnee'tiou withth'e rock-shaft F, so as to alternately close the bottoms of the hoppers D D, substantially as herein shown and described, for the purpose specified. n

2^. The arrangement of the V-shapedeutters JYJ, K K', with relation to the slotted hopper D and oscillating bed F, as herein described, for the purpose specified.

i The above specification of my invention signed by'me, this 28th day of April, 1868.
